Geraint Thomas sealed victory in the Tour de France on Sunday night – becoming the third Briton to win the Tour alongside Sir Bradley Wiggins and Chris Froome.
Cycling fans were delighted for the 32-year-old as he finally added a Grand Tour to his haul of trophies.
And many wanted to tweet congratulatory messages to him – surely, his handle is just @geraintthomas right?
Unfortunately for one Twitter user, it isn't.
Hundreds of tweets have been sent to the wrong Geraint Thomas - breaking his mentions in the process.
This @geraintthomas is actually a lecturer in Visual Effects who suddenly started getting a lot more notifications than normal as Team Sky's Thomas took the lead in the Tour.
The cyclist leading the Tour wears a yellow jersey and there were lots of messages regarding the garment for the other Geraint.
So much so, in fact, that his Twitter profile reads: "Not a cyclist, nor do I own a yellow cardigan."
On Saturday his notifications spiked when Thomas effectively became champion-in-waiting after maintaining his lead on the penultimate stage.
And a day later, when Thomas' triumph was confirmed, a mass of congratulatory messages came flooding in.
Thankfully, the lecturer seems to have taken it all in good humour - and even sent a congratulatory message to the Tour champion.
